Tutorial: Decals on non-flat (curved) surfaces - adstrip, logo

Post by asyvan » Mon Sep 09, 2019 1:05 pm

I thought I'd share a small tutorial I made.

How do you put decals (logos, adstrip, etc) on your vehicle or implements curved (non-flat) surface?
In the video below I will show in three sections, each from start to finish, how to do this. The three sections are:
* How to put a decal on a curved non-flat surface (first 18min of video) Requires Maya or Blender
* How to make a decal (flat or curved) to appear to have a thickness (next 5min) Does not require Maya/Blender
* Creating a 3D effect using high poly created normal map (last 11min)

Here is the video:


Basically the first part of the video shows these steps:
* Export the mod as a .OBJ file using Giants Editor
* Select the faces where your decal will be, using a 3D tool (I am using Maya, but Blender is also fine)
* Create a new object from the faces and assign a new material
* Import the image of your decal to the material (square image, does not need to be correct aspect ratio)
* UV map your object (typically you want to project in a plane) so your decal looks nice
* Create a second UV map (UV set in Maya)
* Export as i3D
* Import into your mod using Giants Editor, give it a shader (vehicleShader) with Decal.
* Done.

The second part does not need Maya or Blender, it shows these steps roughly:
* Get the image you used as decal for your mod
* Make a copy of it and translate it to grey
(easiest is to think of 50% grey for everything untouched, 100% white for the raised parts and 0% black for lowered)
* Import the black/white picture into Awesome Bump 5.2 Found here on Github
* Set blur to the image to decide the "thickness" of the raise/lower in the bump map section of Awesome Bump
* Set depth and normal step in the normal section of Awesome Bump
* Save the normal map when you are satisfied
* In Giants Editor set the normal map for the material of your decal

Topic 'pinned' so it doesn't get lost, since it contains useful information.

I know this is an old thread. I have tried following the 2nd part of this tutorial, I installed AwesomeBump. The tutorial shows you importing the DDS image file into AwesomeBump, I can not import the dds files into the program so i can not continue with the tutorial. AwesomeBump will allow me to import a PNG file, but will not work with DDS. Do you have any suggestions?
